Just wanted to report back on both my custom sensor and the purple air that I own. All three sensors are only reporting zeros. I had to replace all three sensors. So the really hot and humid summer really did a number on the PMS5003 sensors

I fixed the three PMS5003 sensors that were not working for anyone that has the same problem. Used compressed air and blow into the fan opening.... After I did that. All three sensor started working again.....

Or use this one, the "luftdaten" sensor, already hundreds of stations in Europe, how-to-build in multiple languages (sorry the English version is not the best one), Open-Data, Open-source of all scripts via Github.

The scripts used, look the same as for the Purpleair,check this user site and also the normal AQ scripts as used in the US at this demo site

The sensors plus arduino board cost less then 30 dollar and there is a shopping-list with links to the ali*** chiness site.

There are a few users in Northern America also. it is becoming quit a success here as multiple cities sponsor this development by organising how-to-build workshops a.s.o.

Hello,

I am now on progress of making my own Purple air sensor using these german AQI device, I already have the arduino and the sensor, still on delivery sched. anyways where to download that script to add on my web page? hope you can send me or link me one. Thank You and have more power to your leuven scripts.

Here is the project original code. You have to watch what device you are using. The pin are directly hard code for specific sensors. Also the function calls going out to their server has the specific pin hardcoded. So if you use pin 5 instead of pin 1, then you have to make the changes.

Thats the reason why some people get the sensors working with the web interface, but the data never shows up on the server and map.

After a couple of weeks to study, supply and install AQi sensor using SDs011, I successfully obtained and its fully functional, Thanks to Sir Wim for his assistance and scripts I requested, however still needs to polish in one page but I guess it worked, I also put its status as my first page on DASHBOARD using saratoga script techniques. As i initiated the sensor I guess only ME shows on the Map and the rest are relying on Airflow products which cost expensive and also you cannot use it to your own web site polish, so here it is You can check it out
